wiring help

[ld26]

Having some issues with my 55 slider.  When I first got it home i plugged it in and it fired up fine and started cooling, but everytime I touched the thermostat the fuse would blow.  Thought I could fix it with a new thermostat and plug.

I have the new thermostat hooked up and still have the same issue.  If I turn the thermostat to off and plug it in the compressor fires up fine and cools, but if I turn the thermostat dial it blows the fuse again.

Any thoughts on what is going wrong here?

Thanks

It should only be hooked up to the black (hot) wire in series, not the white neutral as well.  I don't have the wiring diagram for a 55, but that white wire should not be there.

tkaz is right. The themostat acts just like single pole switch for a light. Power in to the stat (black) with the power going out of the stat (black) to the compressor and fan, neutral wire just spliced thru.

thanks guys! now I can turn the thermostat dial on an off without shorting anything out

next question, when I have the stat set to off (0) the compressor still runs, is that normal?  I'm wondering if I fried the stat with my bad wiring...
